Wow, you have the tech not only to apply the identity, but to solve for it? That is something!

A major flaw in your approach is the identity is potentially too large, you should instead project something onto a very small space, and then extrapolate in some more or less random (but pretty) manner back to the full dimensional space.

We’re still optimizing. We tried to use a low rank approximation but for some reason it didn’t work. We’ll probably use a banded or sparse representation.

Progress would be faster, but for some reason we can’t retain a mathematician after showing them our experiments.
